85% Capacity at 20°F

Holds 85% of rated heating capacity at 20°F outdoor ambient, and 50% capacity at -4°F — honest cold-weather performance for a value-tier system.

Full DC Inverter

Full DC inverter technology operates the equipment more efficiently and helps minimize energy consumption by modulating compressor speed to match load.

BlueFin Coil Protection

BlueFin Technology provides coil protection against corrosion in environments where traditional coatings fail — useful in coastal and humid climates.

WiFi Smart App Control

Connect the unit to your smartphone or tablet with its app and control your mini split remotely from anywhere.

4-Step Air Purification

Oxidized ions diffused into the air through the coil system collide with bacteria and viruses, inactivating their protein structures and countering airborne toxins.

I FEEL Function

The I FEEL function lets the unit sense temperature at the location of the remote — comfort where you're sitting rather than at the wall unit's return-air sensor.

R32 Refrigerant

Pre-charged with R32, a refrigerant that runs more efficiently and does not deplete the ozone layer.

Auto Clean + Louver Memory

Auto Clean helps keep the indoor coil fresh, and louver position memory returns the airflow to your last setting after every power cycle.

Frequently Asked Questions

Will my warranty be valid if I don't use a licensed installer?

No. This is a traditional line-set system — brazing, evacuation and charging the refrigerant circuit must be performed by an EPA 608-certified technician. The Daizuki warranty also depends on professional installation and online registration within 60 days via the link in the warranty section above. Our team can answer sizing and line-set questions before you order — just call or email.

Does this system lose heating capacity in cold weather?

Yes, and Daizuki states it honestly: the system holds 85% of rated capacity at 20°F and 50% of rated capacity at -4°F. That makes it a usable primary heat source in milder cold climates, but a manual J load calculation is the right way to confirm it meets your home's load at design temperature. If you need closer to full capacity at extreme cold, look for a system rated to hold 100% at 5°F or below.

What is I FEEL?

I FEEL uses a temperature sensor inside the handheld remote to measure the temperature where you're actually sitting, rather than at the indoor unit. The system then adjusts output to reach your setpoint at the remote's location. Useful in larger rooms where the wall unit's return-air sensor might read differently than your seating area.

What is BlueFin Technology?

BlueFin is a hydrophilic coil coating that protects the heat exchanger against corrosion in environments where traditional coatings fail — coastal salt air, high humidity, and industrial atmospheres. It extends the service life of the coil and helps maintain heat transfer efficiency over time.

Is a line set included?

Yes. The package includes a 10 ft install kit. That's shorter than most brands in our catalog (typically 16 or 25 ft), so measure the actual path from indoor to outdoor unit — including vertical rise and bends — before you commit. If your run is longer, you'll need additional line set and possibly additional refrigerant.

robust solution for zone control

Eric Span · November 2025

I was specifically looking for a system that could handle both sweltering summers and freezing winters without running up my electric bill, and the Daizuki delivered. The ability to control the unit from my phone via the Wi-Fi app is a huge plus. I can cool the room down on my drive home or check if I remembered to turn the heat off when I leave for the day. The "I FEEL" function, which uses the remote to sense the temperature right where I am, is genius for ensuring perfect comfort in my favorite chair. I appreciate the inclusion of BlueFin Plated Coils on the outdoor unit—it gives me confidence that it will resist corrosion and last for years, especially given the humid climate where I live. The Auto Clean and Auto Leak Detection features are nice for peace of mind and simplified maintenance.

What Nobody Tells You Before You Buy

If you are looking for mini splits, most sellers cover the basics: an outdoor compressor connected to indoor units via small refrigerant lines, high energy efficiency without duct loss, and separate room temperatures — plus the simple setup needing just a small 3-inch wall opening. All true, but there are critical technical details and long-term ownership realities almost nobody tells you before you buy.

Beyond washing your mesh air filters every few weeks, mini splits need a deep chemical cleaning of the internal blower wheel and evaporator coil every 1–2 years. Because the heads recirculate the air in your living space, neglected moisture can breed toxic black mold inside the barrel fan. And while most guides cover summer condensation draining from the indoor head, heat pumps reverse in winter: during freezing weather the outdoor unit sheds gallons of water in defrost cycles — without a base pan heater or proper drainage that runoff freezes solid, destroying fan blades and icing the compressor base.

Finally, budget for electrical and warranty requirements upfront. A multi-zone system frequently requires upgrading your home's main electrical panel — often from 100-amp to 200-amp service — plus dedicated 208/230V double-pole breakers. Most importantly, beware of online DIY claims: almost every major manufacturer explicitly voids your multi-year parts and compressor warranty unless a licensed HVAC technician performs the final nitrogen pressure test, line evacuation, and refrigerant commissioning.
